Managing Snapshot Proles
A Snapshot Prole is a collection of rules describing when to take periodic snapshots for one or more volumes and the time at which
snapshots are deleted (expired).
A snapshot is a point-in-time copy (PITC) of one or more volumes. Storage Center snapshots dier from traditional snapshots/PITCs
because blocks of data or pages are frozen and not copied. No user data is moved, making the process ecient in both time taken to
complete the snapshot, and space used by snapshots.
